Costco Pharmacy Reviews

Every time I receive my mail order scripts from Costco, the bottles arrive with excessive tablet powder residue all over the inside of the bottle. I’ve not new to these medications and I’ve had many different mail order pharmacies in the past and the meds have never looked this poor and chalky. I mentioned this to the pharmacist three months ago over the phone and once again I get sent this garbage generic powdered junk. Why can’t Costco send out generic tablets that are not falling apart so I don’t have an upset stomach with this powdered mess of a tablet. Lastly, no one in this day and age should wait at least a week or more for their meds without paying ridiculous fees for expedited shipping.

I am not new to Costco but I am or was new to the Costco Pharmacy. As a customer I trusted Costco because I enjoy shopping there. January 2026 I transferred my prescriptions there from Rite Aid (who honestly I realize after dealing with Costco Pharmacy had superior customer service). Not only have I been waiting on my Estrogen patches for 2 months, my hot flashes returned. When I first asked for a refill they told me they didn't have them and would order them. I still had 3 patches left so it wasn't urgent, but when I returned to pick them up they said they didn't have them and couldn't get them. I asked if it was the brand or what and they weren't sure. I asked if I could go to any other Costco and was told it would be the same. So I asked to have my blood pressure meds refilled. Yes, I have 2 on file because my dr switched the kind she wanted me to take, but Costco never asked and filled the wrong one. I really didn't notice until I got home.

Everytime I try to refill my estrogen patches, they say they're on back order and have no waiting list to fill it once it comes in. You have to call everyday to check. This is unacceptable. Other pharmacies notify you on back orders. I will not be using Costco Pharmacy ever again. Shame on you for doing that to your customers. The pharmacist said they get 40 calls a day regarding the estrogen patches. Do better by your customers.

I have been having issues with the mail order pharmacy since my first fill with them. I don’t know how you can bill someone 499 and the patient is the one who has to find your mistakes multiple times. When you are only supposed to be charged 24.99. That’s an huge difference And every month they mess it up and no one will work hard enough to figure out what the issue is. They don’t care at all about their customers. It is so stressful. I think they need people who know how to do the job and care about getting the right answers instead of screwing you without any care in helping you.

I’m sorry you had to deal with all of that — especially for a medication you depend on. Here’s a polished version that keeps the frustration clear while still sounding professional and credible: I am extremely disappointed with the level of service I received from Costco Pharmacy. Last week, I called to refill an important prescription and was told they only had a 3-day supply available immediately, or I could wait until Friday for the full refill. I explained that I would be working 12-hour shifts and would not be able to pick it up Friday or Saturday. I was then advised that I could pick it up Sunday from a locker.

I had a prescription for a pet filled previously at a Costco location with no issues so because we were in the optical department at the store anyway I dropped off a script for my canine thinking it'd be easy peasy. Ha! Worst pharmacy experience EVER. Completely unorganized and incompetent; they could only fill a partial and were supposed to complete the fill within 3 days, 4 days later I called and left a message inquiring as to status, next day I get a voicemail a little after 9AM saying it would be filled that day - mind you, I'm driving over 30 minutes to get to this Costco and at 4:30 PM headed back that way as we had another appointment close by at 5:30 - still no refill.

After filling the same medication multiple times at Costco, the pharmacist refused to fill the med that was due yesterday, reason being because I had seen a "new provider".. Tried to explain that provider is within the same practice/medical office. Then pharmacist said she wouldn't fill it because the office is too far. What?! I explained it's a televideo visit and in the same state of Texas. Nope. Still no fill. Had to call my doctor this am to "reassure" this ** pharmacist who is either in a power trip or just insecure and incompetent. She said she would fill it "tomorrow". Had husband make a fourth call to say I cannot wait any longer. She agreed fill it today. 🙄

Since 1/1/2026, when my new pharmacy insurance went into effect, I have submitted two prescription refill requests. Both times, I have received notifications that my prescriptions are ready for pick up. The first prescription I waited for over an hour because the computers were down. Trying to pick up the second prescription was the same reason; the computers were down. I left without my prescription.

If I could give a zero I would. The staff tries to help at times but they have no clue about their app nor being able to help solve the issue after multiple in person visits. I do not get text messages as I should. Worse, my son’s diabetes meds are not being filled for one reason or another. Now an update was sent by his dr and Costco shows it was cancelled, so once again they cannot help. 2 weeks prior I couldn’t fill a 90 day prescription for insulin because I had to wait 109 days. What the heck. Now we have no insulin and no Dexcom when it all came via mail prior to 7/2025 with no issues every 90 days under another servicer.

To be treated like I'm a drug addict for trying to get my medication 2 days early because I'm going out of town is crazy. My doctor wrote a note stating I can pick up early and the pharmacist take it into their own hands like they are d.e.a. agents breaking a drug lord's ring of illicit drug manafacturing ring is crazy. As the pharmacist quote "You shouldn't be out since you pick up a day before for your refill, is due for the past 8 months." Is crazy, shouldn't they just fill the perscription read what the doctor. Says and shut up? I will definitely not be going to this pharmacy again which sucks because they are so close to the house.

Costco is absolutely the worst mail order pharmacy I have ever dealt with. Nothing makes sense when you look at your prescriptions. Some of them don't show up on the web page. Some of them you can't get 90 day supplies far. I've got two different medications which are generic. One of them cost $1.73 in the other one $103. It's absolutely horrible.

Take a heart medication ticagrelor 80mg and 180tabs. On Good RX can get a coupon cost of $62 at Target (CVS). At Costco pharmacy the cost with Good RX coupon is $1126. Check yourself. This is insane overcharge for exact item.

Biggest idiots ever!!!! Constant issues every single time you deal with them. The call center you end up talking to is a complete joke, not to mention you can't understand half of them. I have never in my life seen more incompetent people in any company.

This is the worst pharmacy I have ever been to. They don’t understand the prescription and when the doctor clarifies they say that they still don’t understand the prescription and can’t fill it. Awful pharmacists at Costco. Soulless people.

I would give negative Stars if I could. This is one of multiple specialty pharmacies that I have had to deal with over the course of the last 20 years and Costco wins for being the worst and they are all pretty awful! It is impossible to get someone on the phone and when you do they are rude and short with you even though it is the company's fault that you are calling for probably the fifth time! In 2026 they lost all of my previous prescriptions even though I had prescriptions filled by them in 2025! They are bad at what they do and they are rude about it! I have no choice in my specialty pharmacy it is unfortunately chosen by my husband's company! And unfortunately they clearly don't have to interact with these companies or they would not choose them!

Terrible customer service for the online rx services. Our insurance switched to their mail order services and they have been very inconsistent and difficult. Online prescription refill take over 2 weeks for a new rx. I just filled a maintenance med on 1/21/2026 and it still hasn't shipped as of 2/2/2026. We have to call and push for them to fill literally every medication that is sent to them. Their website is terrible and does not send alerts like it is supposed to. They do not communicate to clarify orders, they just don't fill them.

Absolutely terrible! They won't fill my prescription through mail-order anymore since my insurance changed. It tells you to call a number, but you can't get through. You sit on hold forever then the phone disconnects. My local pharmacy can't get through to them either. There's no option to transfer online - not even to a local Costco.

Unfortunately I would have to say that I am quite disappointed in the pharmacy and their process. I called to check the status of my prescriptions and someone continued to pick up the phone and immediately put me on hold without saying a word. To make things worse, the call was sent to the general call area.

Do not use Costco online pharmacy if you have other options. I have been trying to get a prescription refilled for the past month. I have talked to them by phone 3 times but they still have not filled my prescription but were able to bill me $344.00. I am now out of the medication I need.

I went to pick up my meds at the pharmacy. 1/21/2026 Store opens early at 9am and presented myself to the pharmacy counter as soon as I was able to make my way to counter. One person in front of me waiting. We talked and after about fifteen minutes I went and picked up a few things. Returned to the pharmacy. Still not open! Finally, at 9:37am I received my meds and went to check out. Very sad they do not have dependable people wanting to work. This is not the first time they were late opening due to pharmacy techs not coming to work on time.

Atrocious system. Took 5 phone calls and over two hours just to update my family's address. They don't consistently provide status updates, take forever to ship, and don't provide tracking information. There are banners under prescriptions saying "we have an update - your order has shipped!" Which are apparently months old, making it seem like they processed your order when they actually lost it. The people are friendly and helpful, but the technology is so bad and we have had so many issues that I have transferred everything to a more reliable pharmacy.

We spent 2 hours on the phone back and forth between our doctor and your pharmacy. On our last call with the doctor, a representative called your pharmacy while we held on the phone. This rep confirmed Rx info with a Costco rep. Then we immediately called Costco Pharmacy. They had no information regarding the doctor rep call. Big fail Costco. We are taking our business away. I suggest you improve your service before more people discover this incompetence. I will say the people were cordial. Yet not helpful. Get it together man!

Unfortunately, my employer switched to Costco for mail order prescriptions and for the last 6 months I have had nothing but horrible service from Costco Pharmacy. I’ve tried booth online and phone for refills and, every time, the order just vanishes into thin air. I’ve had to resort to emergency refills last minute at a local pharmacy. Horrible.

I have been a Costco member for over 20 years, and I have always appreciated the excellent service. Unfortunately, I recently had an experience at the pharmacy that left me shocked, confused, and honestly very uncomfortable. A couple of months ago, when I went to pick up my prescription, one of the pharmacy employees handed it to me in a rude and dismissive way. I politely asked why she treated me like that and why she didn’t say “thank you.” And she answered me, why I have to say thank you to you? .. Since then, every time I return to the pharmacy, the same employee calls over her coworkers and they begin mocking or speaking about me in a bullying manner — including the pharmacist.

2025, September --> After 20 years of filling an unchanged prescription using the Costco Mail Order Pharmacy, I have been forced to change providers. The last refill attempts were more trouble than filling this prescription in any other way. "Christy O.", an alleged customer service supervisor, provided no response to the following issues: Due to a system change, Costco no longer had my payment information or my physical address, which would have been available to any regular individual who routinely backed up a system. Her subordinate would not identify himself. The fact that Costco's system issues should not negatively impact their customers. My request for a USPS or email address to which I could address my concerns, a request made due to a hearing disability.

My first prescription experience was good but then they mailed me pills with blue dye on them for my cat on the next order which I cannot give to my cat because blue dye is toxic to cats and they do not accept returns. I'm transferring my prescription elsewhere.

My insurance provider recently transitioned from Optum mail-order pharmacy to Costco mail-order pharmacy. The processing and delivery timelines at Costco are significantly deficient. The pharmacy lacks an automated refill management system. Additionally, despite registering for medication refill reminders, the service was not implemented, resulting in delayed prescription refills. I have run completely out of medications. Costco also imposes charges for expedited shipping under circumstances attributable to their operational delays. Furthermore, when an e-prescription is submitted by a healthcare provider, the delivery process experiences an average delay of approximately three weeks. I am highly dissatisfied with the quality of service provided.

The only reason I gave 2 stars is because my local warehouse pharmacy is very good. However, I wanted to use mail order, and I could for a short while, and then Costco totally dropped my plan and didn't tell either me OR my insurance company (Aetna). The lack of communication caused confusion and hours on the phone. It was absolutely ridiculous, and I will no longer be using Costco for prescriptions.

We use Cosctco for about 15 maintenance drugs. There have recently been significant delays in filling some prescription and in once instance, they delayed and delayed and then said they could not get my husband's essential medication! They have also stopped texting when meds are ready for pickup or when they are eligible for refill.

I had an Rx sent on a Thurs AM. Said it may take an hour while I waited. After the hour was up, I left the store. I called during the evening to be certain in was filled to pick up the following morning. Pharmacist said she would make it a priority to have it filled first in the am. I am here…waiting. Now 12:30 still not filled. I’ve been out of the needed med. I’m frustrated. I was told they are short staffed.

I wish I could give 10 stars! Costco Pharmacy on Rosedale Hwy in Bakersfield has been a life saver. My husband is on a specialized medication and for the past 5 years have been using CVS. Every month I had to "babysit" the pharmacy, first to call a couple days ahead to be sure the med was in stock, then secondly to call the next day to remind them to fill it. Every single month was a nightmare, but finding another pharmacy was difficult. I finally did it after a medication change which was not in stock at CVS. I called and spoke with Chris at Costco. It was in stock and it could be filled.

Our company's pharmacy insurance switched from Optum to Costco for prescription filling. I started the new account process at the end of June, beginning of July and FINALLY got stuff straight to receive SOME (not all) of my orders by early September. No Prescription information made it from my old company to Costco so I had to start everything from the beginning and its been a challenge and a very disappointing experience.

Our company transferred to COSTCO pharmacy and it has been an awful transition. The communication is awful and their turnaround time is terrible. When you call customer service all they say is" sorry, we serve the whole country and it is what it is." Then the person said you could complain and then they will just tell us to work harder." Sad that we are forced to use these on line pharmacies, instead of supporting our local neighborhood businesses.

Unfortunately this is the way healthcare has been going to screw the patient! But unfortunate Costco should have stayed out of the healthcare business 'cause they don’t know what they are doing, I’m guessing the administration that takes care of my prescription plan accepted the cheapest contractor to handle my prescriptions. What I believe you get what you pay for! Customer service is only there when it’s convenient for Costco… Go figure, nobody handling their calls? Nobody to input data into Costco's system, maybe a skeleton crew works part time? Their software sucks,.. Maybe? Their supplier sucks. Never have what you need, thank God I can go to my local pharmacy!

After (happily) shopping the warehouse for many years, earlier this year, I began getting my prescriptions, at their pharmacy. medications that I have been taking for years, were suddenly ineffective, I started doing a bit of research. Much to my surprise, a huge company like Costco would utilize bad manufacturing but… If simply you Google Aurobindo, their main pharmaceutical manufacturer, you’ll find that they have been cited with warnings by the FDA, numerous times, for quality control issues and additional negligence to comply with regulations. Sadly, I no longer get my prescriptions filled here.

Convoluted mess. Love Costco, but the mail order pharmacy is a complete joke. Half the time I didn't get stuff and had to call, other times they'd send me like 3 or 4 at once.. They'd say they didn't have something and I'd call to transfer it to another pharmacy and that was a HUGE mess, they were terrible to work with and nothing short of incompetent. I'm 40, traveled internationally a good chunk of my life, lived in 17 different states.. That's a LOT of pharmacies. This is the worst.

My mail center is in Washington state. Don't use them. I am disappointed in the quality of Costco Rx Mail service. When it works it's ok but when it doesn't it's usually when you are running low on meds. They just switched to a new and improved online platform. "Improved" is questionable. One of my Rxs needs renewal. On one list in the app it says it's 'in progress' and has been saying that for a month. I'm starting to worry because I'm getting low. On the refill request list it says it's not available for refill. There's not an option to request renewal in the app. I was just on hold 30 minutes to resolve that. Their server is down and it affected the call center and the Rx system.

My first time using Costco pharmacy also as a customer of Costco. What’s a person disabilities, I am prescribed controlled opioid medication monthly. This is my second prescription filled at Costco. The first was July being 2 short, then Aug being 3 short. I’m sure this happens everywhere, unfortunately. I’m just wondering if anyone else had this problem here as well? I’m hoping they will allow me to have them counted before I leave the pharmacy. Although my pills have been short the last two months, I’m sure it’s not human error. It was probably deliberately. I would still refer Costco pharmacy. I just hope it gets directed correctly..

They are just terrible. Won't admit blame for anything. Tell you one thing on phone and a another on email. Don't remind you unless you find their hidden prompt. They can't see anything on their end. It's just a horrible run company.

Costco Pharmacy Nisku, Canada is one of the worst I have experienced nationwide. Poor customer service, slow, do not have medications ready on time and limited supply. It makes sense why you never have to wait in line there. I would sooner wait for my medications, be given the correct ones and have a pleasant experience.
